for decades, the san francisco/oakland bay bridge has been derided for its drab design until this week. >> dusk falls over san francisco, and the city's bay bridge comes out of the shadows. it is being billed as the largest eliminated sculpture in the world theill -- illuminated sculpture. each of the thousands of lights program, allowing an almost infinite array of patterns. >> my goal is to create a communal experience. it becomes a digital campfire that people can gather around. >> his team for the lights to the suspension cables more than 150 meters up in the air. it was back in 1936 that the bridge was first opened to great acclaim, but just five months later, it lost the limelight with the opening of the more majestic golden gate bridge. now after more than 75 years being outshone by its clamorous neighbor, san francisco's other bridge is finally getting a chance to shine. the lights will now come on every night for the next two years. >> that is it for us. thank you very much for being with us. captioned by the national captioning institute --www.ncicap.org--
